Remove non-voting gate-horizon-dsvm-integration from gate queue
Remove non-voting gate-horizon-dsvm-integration from gate queue

The gate-horizon-dsvm-integration job is now non-voting since
it fails randomly, a lot, as shown by the uncategorized bugs page:

http://status.openstack.org/elastic-recheck/data/uncategorized.html

Having a non-voting job in the gate queue is kind of pointless and
since the uncategorized bugs page is only on gate queue failures,
this job is skewing our categorization rates, so remove it from
the gate.
